A method for preheating a beater mill is provided. The method includes: rotating a beater wheel disposed within the beater mill to facilitate circulation of a gas stream between the beater mill and a furnace fluidly connected to each other via both a pulverized fuel conduit and a flue gas recirculation conduit; generating a burner gas via a burner disposed within the flue gas recirculation conduit such that the burner gas joins and heats the gas stream circulating through the beater mill and the furnace; and adjusting at least one of an air supply and a fuel supply to the burner via a controller based at least in part on one of a temperature of the gas stream at an entrance of the beater mill, a temperature of the gas stream at an exit of the beater mill, and an oxygen level within the beater mill.

System and method for preheating a beater mill

A combustion system with a combustion area in a boiler including a fuel pipe for delivering fuel is disclosed. A duct having a bend extended there through is in fluid communication with the fuel pipe and the combustion area of the boiler. The duct has an outer perimeter and an inner perimeter. The duct includes a first partition plate to form a first parallel flow of the fuel between the outer perimeter and the first partition plate, upstream of the bend.

System and method for providing combustion in a boiler

An ignition system includes a pulverized fuel pipe receiving a mixture of pulverized fuel and primary air for injection into a combustion chamber for combustion, and an igniter received within the pulverized fuel pipe for igniting the mixture. The igniter is axially movable within the pulverized fuel pipe.

System, method and apparatus for solid fuel ignition

A pre-ignition conduit for a pulverized fuel nozzle includes a duct having first and second opposing end portions, the first end portion configured to face an outlet of an igniter. The conduit further includes a cone-shaped concentrator for collecting and forwarding pulverized fuel into the duct for ignition, the cone-shaped concentrator being secured to the first end portion and located between the outlet of the igniter and the duct. The pre-ignition conduit functions as an ignition chamber within a pulverized fuel nozzle.
